ABSTRACT:
A magnetic release mechanism comprises an electromagnet excited by means of a release signal, a release auxiliary lever releasable out of engagement directly or indirectly by means of an exciting force of said electromagnet and forced to be rotated in a unidirection, and a release lever adapted to release the regenerating condition of a shutter driving lever in response to the rotation of said release auxiliary lever. Said engagement of said release auxiliary lever is effected at a sufficiently lengthy extremity from a rotative axis, and said release auxiliary lever is positioned, when engaged, apart at a small distance from said release lever.
